[SPDK] threads

Is it allowed to connect to a nvme in one thread (spdk_nvme_connect) and use the controller handle returned in different threads to allocate and use qpairs (spdk_nvme_ctrlr_alloc_io_qpair)? Or does everything have to be done in a single thread? I'm seeing intermittent buffer corruption and I'm wondering if this could be the cause? Thanks, Trevor
